Worked on improving PCIe stability in the tenstorrent/tt-zephyr-platforms repository by addressing a bug that caused AER-induced system reboots during DMA-intensive workloads. The solution involved disabling the PCIe completion timeout through updates to a binary blob and its associated SHA256 checksum within the module configuration, ensuring system reliability and uptime. This work required low-level firmware development in C, with a focus on device drivers and embedded systems. The approach demonstrated proficiency in binary blob management, integrity validation using SHA256, and Zephyr platform configuration, resulting in a targeted fix that aligns with long-term maintainability and reliability objectives for the platform.
